Frequently Asked Questions
Q: Is the K1 GPS HUD compatible with my car?
A: Yes! The K1 HUD is universally compatible with all car models that have a USB port or a cigarette lighter (12V) port. No special wiring or OBD adapter is required — just plug it in and place it on your dashboard.
Q: Do I need to choose between KM/H and MPH before purchasing?
A: Yes, the speed unit (KM/H or MPH) is fixed on the device and cannot be changed after manufacturing. KM/H is available for all regions; MPH is intended for US and UK drivers. Please select the correct unit when placing your order.
Q: How long does it take to get a GPS signal lock?
A: The K1 HUD typically acquires a GPS signal within 1–3 minutes when used outdoors. For best results, ensure you are outside in an open area — signal acquisition indoors or in underground garages may take longer or may not be possible.
Q: Does the display work at night or in bright sunlight?
A: Yes! The K1 HUD features automatic brightness adjustment, which adapts the display intensity based on ambient light conditions. This ensures the projected speed reading remains clearly visible whether you're driving in bright daylight or after dark.
